T0 tI/Z whom it may concern.-

Beit known that I, CHARLEs M. N EALY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Puzzlesfor1 which the following is a speciiication.

My invention relates to puzzles having independently-rotatable concentric disks bearing printed characters thereon, such as letters or igures, the printed characters occurring in a series in such manner that when the disks are properly rotated the characters may appear in a column.

The object of the invention is to provide in a puzzle of this kind means for indicating at a glance the columns to be read.

I accomplish my object by the device illus trated in the accompanying drawings, in which- Figure l is a general face view thereof. F ig. 2 is a section thereof on line 2 2, Fig. l. Fig. 3 is a face view, on a reduced scale, of the backing-sheet.

Similar letters refer to similar parts throughout the several views.

Referring to the drawings, a represents a backing-sheet, which consists, preferably, of

cardboard or stiff pap er, which may be of any desired outline. Rotatably and concentrically mounted on the front of said backingsheet are the disks b c d, pivoted by means of pin e. The number of superposed disks may be varied, and the means of mounting them on the backing-sheet may also be varied without departing from the spirit of the invention. Said disks b c d are graduated in size, the largest disk being on the bottom, the next smaller disk being next above it, and so on. This results in the exposure of an annular portion at the rim of each disk below the topmost one.

Sheet a has a plurality of sight-apertures ff, which are evenly distributed about the center of the backing-sheet in such position as to liejust outside the outer rim of the lowermost disk b.

desired. they are located outside of the outer diameter of the lowermost disk t. Pivotally mounted beneath the backing-sheet a by means of the same device e is a rotatable member g, which is preferably circular in outline and whose diameter is greater than that of These apertures may have an f outline of segments of a circle or may themi selves be circular or have any other outline The essential characteristic is that disk t, so that member g is visible through sight-aperturesf.

Arranged in concentric circles at the peripheries of the superposed disks b c d and upon the member g in such lposition that they will be visible through sight-apertures f are printed characters, some of which are indicated by the reference-letter h. These characters maybe numbers, as illustrated, or they may be letters or even complete words. They are arranged on the various parts in suoli manner as to subtend an equal number ot degrees, whereby said characters i may be brought into lines or columns radiat ing from the center of the device. In the case of printed numbers the puzzle is to so rotate the disk that the sum-total of the dif- 'ferent numbers appearing in certain columns shall all be odd or all be even, or shall amount to the same sum. In the case of printed lete ters the obj ect is to so arrange the parts that the letters in certain specitied columns will spell certain words.I The disks l), c, and d are preferably of contrasting colors, which also contrast with the face of the backingsheet a; but although this is not essential, it is essential to the complete carrying out of my present invention that the color of the rear member g be different from that of the tace of the backing-sheet a at least at the points where said member g is visible through the side apertures f. rBy thus having the member g and sheet a of different colors the eye is readily drawn to the sight-apertures, and it is at the sight-apertures that the columns are to be added or the letters read. Iith my invention, therefore, there is a striking indication of the locations of the columns which must be read in solving the puzzle.

What I claim as new, and desire to secure by Letters Patent, is

l.l In a puzzle the combination of a set of independently-rotatable concentric disks, a back sheet upon which they are mounted, said disks having exposed annular portions at their peripheries bearing printed characters, a plurality of sight-apertures in said back sheet, and an indicator-sheet behind said back sheet and of a different color therefrom for directing attention to the points at which the printed characters are to be read.

2. In a device of the class described, the combination of a set of independently-rotatable concentric disks of ditlerent sizes and so arranged one above another' that a periph- ICO IIO

eral portion of each is visible beyond the edge of the one above it; printed characters on the exposed portions of said disks; a backing-sheet Whereon said disks are mounted, said backing-sheet having sight-apertures located just beyond the edge of the largest superposed disk and a rear member behind said backing-sheet and of a color different therefrom and also rotatable about the same center as the superposed disks, said rear member also having printed characters thereon at the same distance from the center as said sight-apertures.

3. In a device of the class described, the combination o'l a set of independently-rotatable concentric disksl of different sizes and so arranged one above another that the peripheral portion of each is visible beyond the edge of the one above it printed characters on the exposed portions of said disks; a backing-sheet Whereon said disks are mounted, said backing-sheet having sight-apertures located just beyond the edge of the largest superposed disk; and a rear'rnember behind said backing-sheet and of a color different therefrom and also rotatable about the saine center as the superposed disks, said rear member also having printed characters thereon at the same distance from the center as said sight-apertures the disks above the backing-sheet having at their peripheral portions lines radiating toward the center the lines of the different disks subtendingarcs of equal degrees whereby the lines of the dii-ferent disks may be brought to register.

In Witness whereoi I have hereunto subscribed my name in the presence of tWo Witnesses.
